> Currently SolrCache limits are configured statically and can't be 
> reconfigured without cache re-initialization (core reload), which is costly. 
> In some situations it would help to be able to dynamically re-size the cache 
> based on the resource contention (such as the total heap size used for 
> caching across all cores in a node).
> Each cache implementation already knows how to evict its entries when it runs 
> into configured limits - what is missing is to expose this mechanism using a 
> uniform API.
